Abstract

This study aimed to characterize the physicochemical and microbiological properties of brewer’s spent grain, a by-product of beer production, to assess its potential use in animal feed. Samples collected from Cervejaria Petrópolis, located in Uberaba, Minas Gerais, Brazil, were dried, ground, and subjected to physicochemical and microbiological analyses. The results indicated crude protein content of 23.17%, ether extract of 10.30%, ash content of 3.78%, and carbohydrate content of 41.81%. Microbiological analyses detected no contamination in the samples. It was concluded that dried brewer’s spent grain has potential as an ingredient in ruminant feed, contributing to the reduction of environmental impacts and adding value to this by-product.
